Ok, I have run into a little problem. After I pulled the Pulley off from the B18B to swap some stuff, I notice that the Timing Gear that's behind the pulley has these gears that stick out with a SENSOR that I guess reads RPM or something?


When I pulled the crank pulley off of the B20B, the timing gear does not have those wierd gears and does NOT have that sensor... And there is NO way that I can swap over that gear from the B18B onto the B20B because the timing gear will not fit cause of the design of the B20B...

So do I need that Sensor? Does it read RPMS or what? Thanks!!

 

Heres a pic to clarify what i'm saying.

 

not for sure but that looks to be a crank flucuation< spell?, sensor, i think but could be wrong, and dont know what it dose but the b20b should have it well at least mine dose.

 

Its a JDM B20B

 

since the first B20Bs where offered in early 97(although some blocks are stamped 95), they come with a crank position sensor....

if your B18B is OBD 1 then for sure it will not have this....I'm not sure however if 96+ B18Bs came with these?...I know that OBD1 B18C1s didn't come with it and OBD2 B18C1s did...
